Summary

This review formalizes Explainable AI (XAI) methods in computational pathology (CompPath) by introducing a pathology-centric vocabulary, developing a taxonomy of methods, and establishing a task-driven framework. It identifies key gaps between current XAI capabilities and clinical deployment, proposing actionable steps for advancement.

The field of computational pathology (CompPath) is being revolutionized by AI algorithms that assist in diagnosis, prognosis, and treatment prediction from gigapixel whole-slide images. However, widespread clinical adoption is hindered by concerns regarding safety, accountability, and regulatory oversight, especially in high-stakes medical environments. Explainable AI (XAI) systems offer a promising solution to build trust and enable verification, but the existing literature is fragmented by inconsistent terminology and ad hoc validation. This comprehensive review aims to formalize XAI methods within CompPath. It introduces a pathology-centric vocabulary with seven core terms, providing a standardized language for the field. Furthermore, it develops a robust taxonomy that categorizes methodological families across three orthogonal axes: stage, type, and scope of explanation. A task-driven framework is also established, mapping five critical clinical questions to recommended XAI methods, their evaluation strategies, and appropriate deployment contexts. The review identifies five key gaps that currently exist between XAI capabilities and their full clinical deployment. To bridge these gaps, it proposes actionable steps designed to advance XAI for CompPath, ultimately fostering greater trust, regulatory compliance, and clinical utility for AI in pathology.

Why it matters

For professionals in healthcare, AI development, and regulatory affairs, this review provides a critical framework for understanding, evaluating, and deploying Explainable AI in computational pathology, accelerating safe and effective clinical adoption.

How to implement this in your domain

  1. 1Adopt the proposed pathology-centric XAI vocabulary to standardize communication and understanding within multidisciplinary teams.
  2. 2Utilize the XAI taxonomy to systematically evaluate and select appropriate explanation methods for specific clinical AI applications.
  3. 3Integrate the task-driven framework into AI development pipelines to ensure XAI methods directly address clinical questions and needs.
  4. 4Collaborate with regulatory bodies and clinicians to address identified gaps and develop robust validation strategies for XAI in high-stakes medical AI.
